Android OS battery drain still present on 2.3.4 XXJVR

OK, this is unbelievable.
The battery drain on XXJVO was driving me crazy. Reading the forums I noticed some people said the Android OS issue was fixed on 2.3.4. Yesterday, I flashed XXJVR with re-partition and bootloaders via Odin, using the OXAJVQ CSC. I also installed the Voodoo lagfix for XXJVR.
I did a factory reset before and after the flash. Did a battery pull, all the steps that we're used to.
For my surprise, a few minutes ago, the phone discharged in 8 hours to 47%. Guess what? Its the Android OS again. Take a look at the attached screenshots.
Did I do something wrong? Is this normal on 2.3.4?
EDIT: Following $omator and madrooster's advice, I decided to flash everything again from scratch and install all the apps directly from the Android Market. Apparently, the issue was being triggered by a restored appdata backup via TitaniumBackup. I've been using the phone for about a week now, with no issues at all.

im running custom rom gingerreal 7.1.4 JVQ with galaxianEE kernel and lagfix enabled. my modem is ZSJPG and csc XAJVQ.
no issues like u have.
but i have to say, that the battery drain is heavier than on froyo.

Man, that's pretty serious drain. I'm running Ramad's stock deodexed JVR since it was postes with semaphore kernel and my usage is never more than 15%. Why don't you post a pic of the bigger graph?

only way to avoid battery drain is that you remove the battery from phone

have no idea haw did you managed to break jvr but you did it =)
i guess youve runed some app that was not letting phone to sleep
or the system got some broken ones tat caused this (yes wrongly flashed system maybe hehe)
btw notice the blue line under your graph - it should look more like on attached screen

Im also running gingerreal 7.1.4 JVQ with semaphore 1.32 and after 2 weeks of use no battery drain.
Android OS is always below 10% (mostly on 4-5%)

The Android OS bug was fixed from stock JVQ onwards. The reason you guys experience that is because you are using custom kernels built from old source codes released by Samsung or heavily modified by the developer. Go complain to your respective custom kernel thread.

Thanks jb. That could be the reason. I am using Voodoo kernel, maybe that's what causing the drain. Has anyone else on Voodoo experienced the same problem?

jb, I remember that I played Captain America in the morning, but the phone froze and I had to battery pull it. After the restart, I didn't touch it again for like 6 hours. In the night, the phone rang and when I tried to pick up the call, the screen wouldn't turn on, so I had to battery pull it again.
After I turned it back on, I checked the battery stats and noticed the Android OS was running crazy, as you can see in the screenshots.
Captain America afaik is not sensor based, and I battery pulled the phone after I played, cuz it froze. I'd love to blame the game, but I cannot.
Edit: But... looking at the stats, the orientationd process is right next to the Android OS. Could this happen if the phone wasn't resting on a flat surface? :S

Yup the orientationd process was burning you battery juice, the reason why you got Android OS bug. I guess you should try to change your custom kernel or if you really like your current phone setup, you should install Watchdog lite or any similar app to monitor system processes, such as Android OS, for unusually high cpu usage and just reboot your phone when it does occur

i wonder what else is broken in this guys phone that wathcdog and reserting will not fix =)

$omator help me out here. What kernel would you recommend for JVR that keeps everything as stock as possible but includes lagfix? I use Voodoo since it is pretty light, but it doesn't seem to behave so well after all.

stock + cfroot is always a win

Android os drain goes away for my 2.3.3 kg3 stock setup after wiping cache partition and dalvik cache. Ran for weeks and never came back.

This battery drain problem is caused by the kernel you have. It is caused by a bug in a specific device driver.
The phone tries to go into power save mode but something prevents it. When the phone fails to reach a low power mode, you see the battery drain. In summary, if you run a custom, non stock Rom you might not have the battery drain fix. Try to make sure that any custom kernel you use has the same kernel version as stock.

Wow that is pretty big drain.. On my xxjvr (2.3.4 ) it only uses 9 to 10% don't know what's wrong though

Not for me...
1. Clean the phone.
Flashed JVR (from samfirmware). Flashed CF-Root-XX_OXA_JVR-v4.1-CWM3RFS. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX.
All closed by me in settings (NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 22.00 hour battery was at 98%.
Next day in the morning at 10.30 hour, the phone beeps that the battery is at 15%... Looking in the Battery use, discover that in about 12 hours, the Android OS (90%) is draining the battery. OMG...
2. Fully charge the phone, clean the phone.
Flashed JVR (from samfirmware). Flashed speedmod-kernel-k15i-t10. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX.
All closed by me in settings(NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 22.00 hour battery was at 96%. Next day in the morning at 09.30 hour, check the phone.
Surprise! At about 12 hours, the battery "lose" only 4%. And NO Android OS in the battery use.
3. Next day, clean the phone. Fully charge the phone.
Flashed JVR (from samfirmware). Flashed TalonDEV-0.4.4.22-1200-I9000-BIGMEM-CWM3. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX. All closed by me in settings(NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 23.00 hour battery was at 98%. Next day in the morning at 08.00 hour, check the phone.
Surprise! At about 10 hours, the battery "lose" only 5%. And NO Android OS in the battery use.
4. Next day, clean the phone. Fully charged battery.
Download again the CF-Root-XX_OXA_JVR-v4.1-CWM3RFS.
Flashed JVR (from samfirmware). Flashed again CF-Root-XX_OXA_JVR-v4.1-CWM3RFS. Flashed JVR STOCK+ v1.41 aosp losckscreen ODEX.
All closed by me in settings (NO GPS, NO wifi, NO data, NO... nothing) and the mobile network mode set to GSM only. At 21.00 hour battery was at 90%. Next day in the morning at 07.00 hour, looking in the Battery use, discover that in about 8 hours, the Android OS (90%) is draining the battery and the battery is at 25%...
I'm not a specialist in Android, but with this experiment, understand that in my case, the "drayner" of the battery was decided by the kernel, and I decided to flash the JVR stock+ with speedmod-kernel-k15i-t10.
I don't say that the CFroot is bad or that another kernel is good, but for me CFroot don't works good.

A major problem with my I9500!

So I had my i9500 s4 for like 5 months now.. never had a problem, but now.. It restarts randomly and a lot of items there is no sound at all or very low sound, I never messed with it!
That was on stock rom + Preseus kernel.. I installed custom rom with latest preseus kernel and no success, same problem

I was already full stock and faced that problem, will try again though, thanks a lot

I hope you don't experience any of the below things to otherwhise you have to replace your battery
do you have only battery drains or also random reboots?
the fact is that samsung shipped out a bad serie of batteries (which is confirmed by Samsung) their serial starts with BD
the symptoms of a bad battery are:
Huge battery drain
random reboots
while rebooting the phone hangs at samsungs logo
battery is swelling
phone shutting down while you have an incomming call/sms
when you are the "lucky one" to experience one of the above symptoms please replace your battery asap under warranty
if you don't do this you risk a phone exploding in the pocket of your pants this is not only painfull for your phone but also for "everything else" whats in there

Nexus 7 unusable

Hi. To begin with i have to say that, yes, I have searched to find the solution, but havent found it yet.
So my problem is that my tablet is unusable, it is wery slow (5.1.1 CM) and the battery doesnt even last overnight whan not using it. I hava tried fs trim and so on, doesnt work. However when I boot into safemode the performance of the tablet is OK and so is the battery. So does anybody have any sugestions how could I fix it or what rom should I use? Also I have no apps installed apart from gapps.
Thanks

I noticed longer battery life and better performance on KitKat 4.4.4, CM11 or AOSP(Paranoid) version. ~30% longer battery life, no battery drain when sleeping,
my spec: Nexus 7 2012 3G, ext4 latest TWRP +MultiROM
also you should use Greenify app.

Remember to Wipe Cache and Dalvik if you make any changes to System.

You had a root b4 M

I'm none root

I think there is issue with the drain, but it's not sammy fault. if you google Android 6.0.1 problem you'll see many nexus users pointing out that their is a battery drain issue, hope sammy can fix it or it won't affect us as much, Android M suppose to kill those issues it seems like Lollipop 5.0 again.

Here are my battery usage. I think thats not good. Lollipop was better.
Sync, Bluetooth, wlan is off. Screen is autobrightness at 100%
Anybdoy a idea?

One day is not enought to say anything about battery life ... maybe after couple of days .

Android os consumes my battery 8%... is this a fee for root my device by samsung??? What the f.... is that?? I cant use my phone without root or custom kernel??? F.... off samsung!!

Thought I'm alone, anyways, the screen on-time is not bad and can go to 6 hours (if used at once), however when the phone is off, the battery drain is huge and doze mode doesn't seem to be working either..
from 2 to 6 am, the phone was on a table and I was asleep and the drains looks to be huge

No problem with drain for me

What your settings? Display brightness? What apps deactivate? Thanks

Stock settings nothing done to the system display brightness on auto but to full brightness nothing deactivated

Guys i think the issue is with root. IF you rooted your phone before, installed customer rom, installed kernel or installed recovery this issue will happen .
Someone on the forum point it to knox fused burn and it can no longer go back to normal.

Rightly said.
If you have tripped Knox while rooting previously, never ever installing a STOCK ROM (May it be lollipop or MM) will fix the battery drain issue since there is some read cycle which the kernel does continuously if the Knox is tripped which can only be overridden with a Custom Kernel.
So, either wait till we get a custom Kernel on MM and root (Ofcourse) or enjoy the new Look n Feel at the cost of battery drain
Btw, I am un-rooted on Stock N9208 (Waiting for MM in my region)

Can we confirm? :fingers-crossed:

no it doesn't not but maybe the way he fully clear all data from the phone then installed a clear version.

ram management is better than lollipop an doze mode work perfect!

but i disable facebook , skyp , Svoice and google music

You will never get stock everything deepsleep. So all future updates are null and void for everyone. Unless you get a modified stock kernel to fix the deepsleep. Or a custom kernel. Unrooting doesn't help as Knox ix 0x1
